recent years none compared with this one. 

 Together several of us observed it until almost 

 twelve o'clock, but its greatest brilliancy and 

 intensity was seen before eleven. Among the 

 striking things was the rapidity of the move- 

 ments, the brilliancy at the zenith, and the 

 distance to which the bands of light extended 

 into the south. It seemed as though the light 

 originated near us, so bright was the display 

 at the horizon in the north. The color was 

 variable from light-green to light-yellow and 

 gray. Carl Zapffe

To the Editor of Science: Since the ac- 

 counts of the aurora of August 26 in Science 

 for October 6 and 20 covered only an area from 

 Michigan eastward, it will be of interest to 

 know that it was observed at least as far west 

 as the Front Range of the Rockies in northern 

 Montana. We were camped at the time a 

 few miles east of the old postoffice of Saypo or 

 west of Chateau in Teton County, some eight 

 miles east of the mountain front. The phe- 

 nomena here were very much like those de- 

 scribed by others. I give them from memory. 



As the brilliant, yellow, diffused light of 

 sunset faded in an absolutely cloudless sky, an 

 arch of white light became visible extending 

 across the sky from east to west, perhaps 60° 

 from the northern horizon. North of this 

 were three or four broad vertical bands of 

 white, the lower ends somewhat fringed as 

 they are so often shown in illustrations, but I 

 noticed no streamer-like motion. The arch 

 slowly moved southward, mounting in the sky. 

 Between nine and nearly eleven I saw nothing 

 further of the aurora, but when we looked at 

 it again, shortly before eleven the east and 

 west arch was only some 20°-30° above the 

 south horizon and all the rest of the sky to the 

 north of it was aflame with white lights, which, 

 as I remember it, waved and flickered irreg- 

 ularly, but incessantly from all sides towards 

 the zenith. A few minutes later all traces 

 of the auroral glow seemed to have disap- 

 peared. 



Though I saw only white lights myself, some 



people whom we spoke to next day mentioned 

 a pink glow. Marcus I. Goldman

To the Editor of Science : It is interesting 

 to note that the auroral display of August 26 

 was visible in southwestern Montana. Owing 

 to the prevailing atmospheric conditions it ap- 

 peared to be of a different character there. 

 The writer and a companion, being engaged in 

 geologic work in the Beartooth Mountains 

 under the direction of the University of Chi- 

 cago, were at that time camped just below the 

 rim of one of the high plateaus on the north- 

 eastern side of the range, at an elevation of 

 about 9,500 feet. The most violent thunder- 

 storm of the season had swept over the plateau 

 the previous evening. In the morning great 

 banks of fog rolled up from the canyons, com- 

 pletely hiding the plateau for the greater part 

 of the day. Toward evening the fog lifted 

 slightly, and about nine o'clock a luminous 

 rosy light was noticed in the northeast. It 

 was a steady glow that spread from the hori- 

 zon, which was quite high, far up in the sky. 

 No streaks or shafts of light of any sort were 

 seen during the half hour that the light was 

 observed. 



A feature of the occurrence as viewed in that 

 locality, which has not been reported else- 

 where, was the repetition of the phenomenon 

 on the following evening, but on a much 

 smaller scale. From the bottom of the canyon 

 a faint glow was seen over the rim of the 

 plateau, but it was observed for a short time 

 only. Arthur Bevan

To the Editor of Science : The auroral dis- 

 play of August 26, first described in your 

 columns by Professor C. C. Nutting, was also 

 observed from the Columbia River Gorge, 

 forty-five miles east of Portland. I was a 

 member of a party of geology students from 

 the University of Chicago and on the night 

 of the display our camp was located on the 

 north side of the river at Collins, Washing-
